WOOD SCREEN.

Application filed. December 5, 1925. Serial No. 73,453.

This invention relates to a rotary screen and for the sake of illustration, it might be stated that in ore mills, concentrators or the like, the ore is ground in the usual way, which ore always contains a great quantity of wood, which passes with the ore to the grinders.

It is common, for the wood thus ground, to clog and stop the operation of the valves of the mechanism employed for treating the ore, and therefore it is the object of the present invention to provide means for screening the wood from the ore and depositing the same remote from the place where the ore is delivered.

An important object of the invention is to provide a screen of this character which may be readily and easily repaired, the screening sections being removable without removing the screen proper from its supporting bearing.

A still further object of the invention is to provide a screen so constructed that the wood will be thrown from the screen as the screen rotates.

lVith the foregoing and other objects in.

view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention. Referring to the drawings: Figure 1 is a front elevational view of a screen constructed in accordance with the invention.

Figure 2 is an end elevational view thereof. Figure 3 is a vertical sectional view through the screen.

Figure 4 is a sectional detail view, illustrating the manner of securing the screen to its supporting shaft.

Figure 5 is a fragmental sectional view illustrating the manner of securing the screens to the end members thereof.

Referring to the drawings in detail, the reference character 5 indicates a base on which the supporting arms 6 are supported, which supporting arms include bearings at their upper ends for the reception of the shaft 7 on which the screen is supported. The screen includes disk-like end sections 8 which are provided with collars 9 that have openings for the reception of the bolts 10 whereby the disks are secured to the shaft 7.

Angle bars 11 are secured to the inner surfaces of the disk 8, and as shown, these angle bars are curved throughout their lengths to provide supports for the screening members to be hereinafter more fully described, it being understood that the angle bars radiate from a common center.

The screens are indicated at 12 and embody frames 18 through which the bolts 14 may extend, the bolts 14 also passing through the angle bars 11 to'secure the screens in po sition in such a way that the screens may be readily and easily removed by removing the bolts, thereby facilitating replacement of the screens or repair thereof.

Directly under the screen is atrough indicated at 15 into which the ore passes upon passing through the screen, there being provided a trough 16 arranged under the screen and disposed in front of the trough 15 for the reception of the wood which does not pass through the screen but which is carried thereto by the constant rotation of the screen.

The reference character 17 indicates the launder through which the water, ground ore and wood from the grinding mills, pass, the launder delivering the material to the screen.

Mounted at one end of the shaft 7 is the pulley 18 over which a suitable belt not shown, may operate, the belt being driven by any suitable means not shown to rotate the screen.

From the foregoing it will be seen that material is deposited onto the screen which is rotating as described, whereupon. the ore and water passes through the screen and .into the trough 15, the wood being carried upwardly by screen members, and owing to the fact that these screen members are curved outwardly, the screen will deliver the wood to the trough 16 where it may be carried away and deposited in a suitable place remote from the screen.

I claim 1. In a screen of the class described, a supporting shaft, end members secured to the supporting shaft, angle bars secured to the end members, said angle bars having curved NT Felon.

portions, and screening members secured to the angle bars and extended to the outer edges of the end members.

2. In a screen of the class described, disk- 5 like end members, a shaft on which the end members are mounted, curved angle bars secured to the end members, curved screening members secured to the angle bars, and said screening members extending from the shaft to the outer edges of the disk-like end 1nem 10 bers.

In testimony that I claim the foregoing as my own, I have hereto afiiXed my signature.

HUGH A. CAPERTON.
